ROTARY STEAM CLOTH-.FINISHING PRESS.

SPECIFICATION forming part of Letters Patent N0. 621,028, dated March 14, 1899. Application filed OGObeI 3, 1894. Serial No. 524,814. (No model.)-

To tZZ whom, t may concern.-

Be it known that I, MALCOLM CAMPBELL,

y of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Rotary Steam Cloth-Finishin g Presses, of which the following is a specication.

My invention relates to an improvement in rotary steam cloth-finishing presses, and has for its object, among other things, to provide means whereby the fabric may be pressed and finished without injuring the goods.

My invention consists in certain novel features of construction and arrangement of parts, which will be fully hereinafter described, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, and the characters marked thereon, which form a part of this specification, like characters designating like parts or features, as the case may be, wherever they occur.

In the drawings, Figure l is an end View of a press embodying my invention. Fig. 1a is a longitudinal section through the machine. Fig. 2 is an end View of a portion of the main apron. Fig. 3 is a top view of that part of the main apron shown in Fig. 2. Figs. 4 and 5 are details showing the manner of connecting the cloth, the paper apron, and the main apron and also the relation of the lugs in respect to the pressing-rolls. Figs. 6 and 7 are end and front views, respectively, of the pressing-rolls and their accessories.A Fig. 8 shows a part of the means for adjusting the main cylinder and the star-wheels. Fig. 9isa detail view showing the shaft x, its pinion w21, anda portion of the wheel y;

The framework of the machine A, the maincylinder w, the friction-rolls l0 and 12, the guide-rod t, rolls n,guide1od s, brushes Z and l', friction-roll S, stretch-roll S', Steamers f and ks, winding-up rolls c3, or folder 3 may all be of the form and construction common in such machines. The main or large pressing-cylinder may be constructed of any material suitable for holding steam. The cylinder w and the Steamers ,7'3 and 7a3 may be connected with the steam-pipes in the usual way. These Steamers jg las are located at the top and the delivery side, respectively, of the machine, whereby the cloth is steamed before to the cylinder.

it passes by the cylinder and also after it has passed the cylinder, butbefore it reaches the winding-up roll. The cloth passes first to the steamer l7'3 at the top of the machine, thence around said steamer by means of suitable rolls or rods to the stretching-roll S', and thence From the cylinder the cloth passes to the steamer 7c3 at the delivery side of the machine and from thence to the winding-roll. Upon these parts and the general structure of the machine I make no claim, my invention consisting in the novel means of pressing the fabric and in the novel means whereby the fabric is pressedand finished withoutinj uring the goods, the fabric lying in a natural or normal condition,so far as stretching is concerned, while running through the press. constructed the fabric is subject to varying and frequently damaging strain owing tothe varying speeds at which the several parts of such machines are driven. By my invention the stretchingroll, the main cylinder, the pressing-apron, the winding-up roll, and the fabric are arranged to move in unison, as are In presses of this kind as heretoforealso the several rolls over which the fabric goods and at the same time prevent injury to the fabric or press when places of union of two pieces of fabric or other inequality passes through the press. It is to be observed that the winding-up roll and stretch-roll are driven in unison.

Both ends of the machine being in duplicate, ja description `and illustration of the parts of one end will sufce for both. Meshing with a spur-gear (not shown) upon the main shaft, on which the cylinder w is mounted, is a gear-wheel y, mounted upon a shaft P. This shaft is also provided with a pinion Q, rigidly mounted thereon. Q and R represent two arms, each at one end being loosely mounted on a shaft s. At the other end they are loosely mounted'upon the shaft P and the shaft T, respectively. s2 is a spurgear meshing with the pinion Q and with a gear-wheel'lrigidly mounted upon the shaft T. By this means provision is made for com- IOO Vzo

municating power from the wheel y to the wheel T2 when said wheel and its shaft T are slid laterally, as will be hereinafter eX- plained. y

The shaft 0c, on which the main cylinder turns, is mounted at each end in a bearing E, constructed and arranged to slide vertically in ways E/ in the frame of the machine to admit the raising and lowering of the shaft and its cylinder. G is a rod provided at its ends with right and left hand screw-threads arranged to be screwed into the bosses F and H, respectively, the boss F being pivoted to the bearing E at F and the boss H being integral with a strap H. The strap I-I tits about the eccentric I2, secured to the shaft I', suitably mounted in the frame of the machine. Secured to the shaft I' is a spur-gear I, meshing with a pinion L on a shaft K, mounted on the frame of the machine above the shaft I. A hand-wheel J, secured to the shaft K, serves as a means to impart motion to the eccentric l2.

Star-wheels G and G2 are mounted upon shafts hand T', respectively, that are secured in bearings f, constructed vand arranged to slide upon horizontal ways f. The usual drums to support the apron are mounted on these shafts h and T. d and CZ represent right and left hand screw-threads secured at one end in bosses c, pivoted by bolts c at nearly opposite points on the spur-gear I and at'their other ends secured to bosses c', pivoted by bolts e to the sliding bearings ff.

From the foregoing it will be seen that as the shaft I' is rotated the cylinder will be raised or lowered through the medium of the eccentric l2, while at the same time, through the medium of the rods l d', the star-wheels if' G2 will be moved away from or toward each other. By this means a constant tension is kept upon the apron a, which passes over said star-wheels G and G2 and around said cylinder, as shown in the drawings. These star-wheels are provided with teeth g to engage pins a7, projecting from the sides of the .apron a, in order to impart motion to said apron. The teeth g on these wheels are faced in opposite directions. The teeth on the wheel G', which is driven indirectly from the main shaft, drives the apron,while the wheel G2 derives its motion from the movement of the apron, the pins a7 of which draw against the teeth of this wheel.

It may be found necessary to have a friction-band on the shaft of the star-wheel G2 to keep the weight of the apron from running the apron out backward when the pressure is released. The apron a is composed of slats a', beveled at a3 sufficiently to permit them to go over the wheels G G2 Without the edges touching. These slats are secured at their ends by ears a4 to links a5, pivoted together by the pins a7, thus forming an endless apron that will readily conform to the cylinder w and to the Wheels G G2. Inside these slatsthat is, between the main apron and the cylinder-is an apron of felt b and, if necessary, an apron of paper. These aprons are made endless by means of one of the slats a being so constructed that it will clamp and hold the ends of said felt or paper aprons. An end view of this construction is shown in Figs. 4 and 5. As here illustrated, one of the slats ct is made in two parts provided with perforated lugs as, which register when the two parts are assembled and permit the two parts of the wheel between which the ends of the felt or paper apron have been placed to be securely clamped together by means of bolts and nuts a2, thus also securing the ends of said felt apron and forming an endless apron of felt.

The clamping-lugs a8 are placed at intervals across the slat to allow the slat to pass the plessing-rolls o. (See Figs. 1 and 4.) The object of these pressing-rolls is to press the slats of the main apron firmly against the main-apron roll or cylinder w. These rolls are under the cylinder w and are held in place in the main bed D of the machine by the Shanks o2 of the stands o passing through said bed D. These rolls are made adjustable up and down by means of nuts and checknuts r on the ends of said shanks. Springs q are arranged on these shanks between the said bed D and the stands o. By this means the rolls exert a yielding uniform pressure on the slats,permittingthe slats and rolls to yield outwardly away from the cylinder in case of an unevenness in the fabric or any other obstruction. These springrolls are located at suitable intervals across the bed D of the machine and spaced to permit the lugs as to pass between them. (See Fig. 4.)

The wheel y meshes with a pinion 0022 on the shaft :n On this shaft is a band-wheel c, which drives a belt fv, which in turn drives the brushes Z Z. The belt to drive the stretchroll S is driven from the star-wheel shaft l", said belt passing around the tension-pulley V, said tension-pulley being held in position by the lever T and weighted down by the weight u, so that as the drums on the shafts T4 71. are thrown apart the belt will be kept atthe same tension at all times.

All the several parts of the press are so timed that they move in unison, so that all stretching of the material, which occurs in most ot' the rotary presses as at present constructed, wherein the cloth is dragged between the press-roll and one or more stationary beds, is prevented. The beds beingheld firm and the rolls rotating causes the fabric to stretch out of shape and also elongate to quite an extent, according to the-amount of pressure and friction brought to bear on it. By my invention all stretching is avoided, since the fabric, the apron, the stretch-roll, the winding-up roll, and the cylinder all move in unison. The fabric R passes into the press, as indicated by the darts in Fig. 1, passing over the friction` roll Z0, down through the guide-rod 't and the roll n and the guide-rods s, one side being IOO IIO

raising or lowering the said cylinder by the.

means already hereinbefore described.

Z010 and X10 are band-wheels mounted upon the shaft j. The wheel 7510 receives the belt that drives the winding-up roll, while a short belt w3 on the wheel Zw communicates motion` to the stretching-roll S.

Having thus explained the nature of my inventionand described a way of constructing and using the same, though Without attemptingto set forth all of the forms in which it may be made or all of the modes of its use, what I claim, and desire to secure by Letters Patent,`
